CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 636,768, dated November 14, 1899. Application filed February 5, 1896. Serial No. 578,081. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JAMES G. DELANEY, a citizen of the United States, and a resident of New York, in the county of New York and xed bearings in the frame, and the shaft 16 has a vertically-slotted bearing in the frame, so that it may move bodily to and from the shaft 15, toward which it is yieldingly held by the spiral springs 17 and 18. A wheel 19 on the shaft 15 runs on the main cable 3. wheel 2O ou the shaft 16 serves as a presser to press the main cable and the wheel19 into close contact and prevent slip between them. A wheel 21,concentric with the wheel 19,runs on the upper stretch 7a of the traction-rope. A wheel 22 on the shaft 16 serves as a presser to press the rope 7 t and the wheel 21 into close contact and prevent slip between them. The wheels 21 and 19 are fixed to each other, so that they turn as one. Wheels 2O and 22 are separate, so that they turn as separate wheels. This, however, might be reversed, the wheels 2O and 22 being iiXed together and the wheels 19 and 21 separated from each other and the cable 3 and traction-rope 7 a changing places. 23 is the wheel-rest for the hoisting-rope, and 40 the wheel-rest for the lower stretch 7b of the traction-rope.

rPhe operation is as follows: It is requisite that all rope carriers should travel in the same direction as the load-carriage, but at a slower rate of speed, and that the rope carriers should differ among themselves as to speed of travel in proportion as they are farther removed in the series from the load-carriage. The upper stretch 7 a of the tractionrope travels at the same speed as the loadcarriage, but in an opposite direction. When, therefore, the load-carriage is advancing in the direction of arrow oc toward the tail-support, the wheel 21 of each rope carrier will be driven in the direction of the arrow y. The wheel 19 being compelled to turn in the same direction, it acts as a traction-wheel on the main cable and compels the rope carrier to follow the load-carriage. The reverse motion takes place when the load-carriage is returning toward the headtower. By constructing the wheel 19 of smaller diameter than the wheel 21 the speed of the carrier may be reduced below that of the load-carriage to any extent desired, and by varying the difference between these wheels, as between different rope carriers, each one of the series may be speeded properly with respect to the others, so that they will automatically divide and useful Improvements in Conveying Apparatus, of which the following is a specification.

My present invention relates to that class of apparatus shown in patent to the Lidgerwood Manufacturing Company, dated August 2, 1892, and numbered 480,029, in which the fall-rope carriers contain mechanism for their own propulsion; and my present invention consists in an improvement in the direction of certainty of action, freedom from wear, lightness, and simplicity of construction.

In the accompanying drawings, Figure 1 is a side view of an apparatus. Fig. 2 is an end view of a rope carrier. Fig. 3 is a side view of the same. Figs. 4 and 5 are an end and side view of a modification.

1 is the head-support.

2 is the tail-support.

3 is a trackway, of rope or 4 is the load-carriage.

5 is the fall-rope, driven by drum 6.

7 is the traction-rope, driven by drum 8 and connected at each end with the load-carriage. For convenience I shall designate the upper stretch of the traction-rope as 7a and the lower stretch as 7*.

At 8a is a guide on the load-carriage whereby the stretch 7 a of the traction-rope is held down by the side of the main cable. The construction of this guide is immaterial; but it may be of the form shown in United States Patent No. 551,869, dated December 24, 1895, to T. S. Miller.

9 and 10 are fall-rope carriers, of which there may be any required number, all similar to that shown in Figs. 2 and 3, but differing among themselves in the relative size of their wheels or sheaves to secure the proper dierential of speed. Turning now to Figs. 2 and 3, I will describe one fall-rope carrier as a representative of all. The frame consists of the side pieces 11 and 12 and the top and bottom cross-pieces 13 and 14. 15 and 16 are parallel and one vertically above the other across between the side pieces of the frame. The shaft 15 has cable.
